Why Are Non-Trinitarian Believers Sometimes Labeled as Non-Christian?

[First and the Last]

The question of why non-Trinitarian believers are sometimes labeled as non-Christian is one that touches on deep theological convictions and centuries of church history. For many, the doctrine of the Trinity—belief in one God existing in three distinct persons: Father, Son, and Holy Spirit—is seen as a cornerstone of orthodox Christianity. However, there are devout believers who, while fully affirming the deity of Jesus and the authority of Scripture, do not adhere to the traditional Trinitarian formula. This raises important questions:

Is belief in the Trinity a necessary criterion for being considered a true Christian?
How do we define the boundaries of Christian identity and fellowship?
I'd love to hear your thoughts on this—why do you think this issue is so divisive, and how should the Christian community navigate these differences?

The Scripture doesn't say, believe and understand the Trinity and you shall be saved!

If you've repented of your sins and believe in the finished work of Christ, then you are saved.

I personally don't look at you as anything other than a Christian.

I do think modalism is wrong and disrespects the person of the Father and the Holy Spirit.

Of course you have your own explanation for that, but I'm not buying it!

 

[joestue]

Because very few have any spiritual discernment. So the only identity in christ they have is a handful of other people who believe enough of the same things they do, and that comforts their lack of relationship with Christ. Produces eco chambers etc

"I dont know if your jesus is my jesus unless you agree with my insecurity produced belief structure."

Jesus didnt really talk much about beliefs, other than faith in God. He kept it simple you will know them by their fruits.

Just keep this in mind:

It's true that as believers, we experience the empowering presence of the Holy Spirit, manifesting through speaking in tongues and other gifts, as described in Acts 2:4 and 1 Corinthians 12. These experiences are vital and life-giving, and they demonstrate the active work of God in each of us. So while the work of the Holy Spirit in our lives is indeed a point of shared experience, the underlying theology is significant because it influences our understanding of who God is. while the Holy Spirit works powerfully in all who believe, the understanding of God's nature—whether as Oneness or Trinity—shapes how we interpret these experiences and how we relate to God. Our desire is not just to experience God but to know Him as He has revealed Himself in Scripture with no division either externally or internally. I see the Holy Spirit as the very presence of Jesus as the same God (I AM of the OT) who indwells us and empowers us. That said, the common ground we share in the Spirit’s work is indeed a beautiful thing, and I value our fellowship in that.

Sure but what do you do to prevent this from happening?

I totally agree with this statement as written. But I would take it even further. Muslims say they believe in the same God Christians do. They would say "Allah" simply means God.
However, when you press them about the trinity and deity of Jesus, they would say Jesus isn't God. So then, they cannot be the same God. One of them is a false God.

It's the same with the Trinity, some people who claim to be Christians, do not believe in the Triune God, and some do not believe in the deity of Jesus. OK, but that's a different God than my God.
That's a different Jesus than my Jesus. We can't both be right. Someone is wrong, someone is wrong about God, the Trinity, Christ. They can't both be Christians.
They are worshipping two different Jesus's.

Matt 24:24; "For false Christs and false prophets will arise and will show great signs and wonders, so as to mislead, if possible, even the elect.
Mark 13:22; for false Christs and false prophets will arise, and will show signs and wonders, in order to lead astray, if possible, the elect.
2Cor 11:4; For if one comes and preaches another Jesus whom we have not preached, or you receive a different spirit which you have not received, or a different gospel which you have not accepted, you accept this willingly.

So, I am definitely someone who would say a non-Trinitarian is not a Christian. But let's say you're a new Christians, you don't know the Bible well, you don't really have a defined theology yet.
I believe there is grace for this. But if you have been a Christian for several years and know the Bible, then there is no excuse.

while the Holy Spirit works powerfully in all who believe

Ahhh... the crux of the situation. Not everyone who says they are a Christian actually is. Not everyone who claims to have the Holy Spirit actually does.
Otherwise, there wouldn't be divisions.

Jehovah's witnesses claim to have the Holy Spirit, Mormon's claim to have the Holy Spirit, it seems everyone claims to have the Holy Spirit, yet their Spirit is totally different from mine.
Their spirit says Jesus came from another planet. Their spirit says Jesus had sex with Mary Magdalene, even though they weren't married, their spirit says Jesus was once just a man and became "a" god.
The JWs says Jesus wasn't ever really resurrected, He was resurrected as Michael the angels, and Jesus and Satan are angel brothers. Ony the 144,000 are going to heaven.
I'm sorry but those are different Jesus's, different Christ's.

Sure but what do you do to prevent this from happening?

Understanding God’s nature as One—fully revealed in Jesus Christ—grounds us in the truth of who God is and shapes our relationship with Him. The interpretation of our spiritual experiences is not just a matter of personal preference, but deeply rooted in the revelation of God’s nature as shown in Scripture. When we view God through the lens of the Bible, we see the fullness of the Godhead bodily in Jesus (Colossians 2:9). This understanding prevents confusion and ensures that our experiences align with the biblical truth that God is one and that His name is revealed in Jesus. To prevent divergent interpretations from leading us away from this truth, we must continually immerse ourselves in Scripture, allowing it to be the final authority on how we understand our experiences with God. By remaining anchored in the Word, we guard against interpretations that could dilute the clear biblical revelation of God’s nature and ensure that our relationship with Him is grounded in the truth of One God, as revealed in Jesus Christ.

So, I am definitely someone who would say a non-Trinitarian is not a Christian.

The doctrine of the Trinity, which professes that God is one and indivisible, might seem to internally divide Him into separate persons (Even if its Internally how do you divide One God). The idea of God's indivisibility is central to our understanding of His nature. Bible holds firmly to the belief that God is absolutely one, without division or separation within Himself.

The concept of dividing God internally can feel like it compromises His true oneness. The Father, Son, and Holy Spirit are different manifestations of the one God. God was fully present in Jesus Christ, reconciling the world to Himself, and that the Holy Spirit is God's presence active in our lives today. This understanding preserves the unity of God and upholds the belief that He is wholly and completely one.

All bogus so I see your point and thanks for the clarity.

Brother, I am an entire scripture believer who understands that Yehovah never changed from the Old Testaments through the Renewed Testament. If I want to sum up the Old or the Renewed Testament I will use the verse quoted in the Gospels,

Deut. 6:5 English Standard Version
You shall love the LORD your God with all your heart and with all your soul and with all your might.

This is our mission, as per both collections of messages, and demonstrates that, clearly, our Elohim has never changed.

Yehovah, Yashuah, Jesus, Holy Spirit, Ruah, God, no matter how we address Him, He is a mystery that we need only to believe because we are not given to know this plainly. We are saved by faith not by being smart.

Still sounds circular to me.

What do you mean?

 

[KingJ]

Why Are Non-Trinitarian Believers Sometimes Labeled as Non-Christian?​

Because believing Jesus is the Son of God, Messiah and Lord is the faith we are given from God. Matt 16:16-17, 1 Cor 12:3, Isa 9:6.

God makes us a Christian.

 

[KingJ]

If you've repented of your sins and believe in the finished work of Christ, then you are saved.

This is incorrect. In theory it's correct. The issue is on repentance. How do you know if your repentance meets God's standard? Jer 17:9-12.

According to scripture, we are grafted into the family of God and receive a revelation of Jesus being Lord from the Holy Spirit 1 Cor 12:3.

If anyone cannot truthfully call Jesus Lord, they are not a Christian. They think they are. Unfortunately for most, Christianity is not something like a book club.

I understand what you're saying.

My post was assuming they have Biblically repented and believe.
